[SOLVED] Determining the type of object

[mabus]

I usually user php's "assert" function to test variables.

 

Now, is there a way to determine the type of object that is initialized to a variable? The function "is_object" is not good enough, 'cause it will only determine a particular variable or not, but what I want is to determine if a particular object satisfies the set requirement.

 

for example:

 

public function GetSomething(MyDesiredObject $newObject) {

... some implementation here ...

}

 

Now, I want this function to be able to accept only that "MyDesiredObject" data type. usually I'd do an assert from within the function to test, but how about if I want to determine if the value of that "$newObject" variable is really of "MyDesiredObject" data type?

 

How do we do this on PHP?

try

<?php
class a{

}
class b{

}

$x = new b;
if ($x instanceof a) echo 'is a'; else echo 'it is not a';
?>

try

<?php
class a{

}
class b{

}

$x = new b;
if ($x instanceof a) echo 'is a'; else echo 'it is not a';
?>

 

This one works, and is good enough for me.

 

Thanks for the help
